Definitions

  • the present invention relates to a thermoplastic composition. More particularly, it relates to a thermoplastic resin composition excellent in solvent resistance, weld strength, impact resistance, molding property, etc.
  • US-A-4 172 103 and US-A-3 947 524 are disclosing generally aromatic polycarbonate resins and a thermoplastic resin on a rubber or a graft polymer.
  • thermoplastic composition comprising a polycarbonate resin and a graft polymer as the essential components and improved in chemical and physical properties, particularly in solvent resistance and weld strength
  • incorporation of a small amount of a polyolefin or a certain plasticizer into such composition is effective in improvement of solvent resistance and weld strength.
  • the resulting composition is excellent in processability.
  • the present invention relates to a thermoplastic composition according to claim 1. Further embodiments can be found in the dependent claims.
  • polycarbonate resin there may be used any one chosen from aromatic polycarbonates, aliphatic polycarbonates, aliphatic aromatic polycarbonates, etc.
  • examples are polymers comprising units of bisphenols such as 2,2-bis(4-hydroxyphenyl)alkanes, bis(4-hydroxyphenyl)ethers, bis(4-hydroxyphenyl)sulfones, bis(4-hydroxyphenyl)sulfides and bis(4-hydroxyphenyl)sulfoxides.
  • bisphenols may be substituted with halogen.
  • the graft polymer there is used the one grafting at least one aromatic vinyl compound and at least one of vinyl cyanides and alkyl unsaturated carboxylates onto a conjugated diene rubber.
  • the conjugated diene rubber are polybutadiene, butadiene-styrene copolymer, butadiene-acrylonitrile copolymer, etc.
  • the aromatic vinyl compound are styrene, a-methylstyrene, dimethylstyrene, vinytoluene, etc.
  • the vinyl cyanide are acrylonitrile, methacrylonitrile, etc.
  • the alkyl unsaturated carboxylate are lower alkyl acrylates (e.g.
  • the weight proportion of the conjugated diene rubber and the monomeric components in the graft polymer may be usually from 5:95 to 70:30. Further, the weight proportion of the aromatic vinyl compound and the other monomeric component(s) consisting of the vinyl cyanide and/or the alkyl unsaturated carboxylate may be normally from 50:50 to 80:20.
  • the copolymer there may be used any copolymer of at least one aromatic vinyl compound with at least one of vinyl cyanides and alkyl unsaturated carboxylates.
  • aromatic vinyl compound, the vinyl cyanide and the alkyl unsaturated carboxylate are those as stated above.
  • the weight proportion of the aromatic vinyl compound and the other monomeric components(s) consisting of the vinyl cyanide and/or the alkyl unsaturated carboxylate may be usually from 55:45 to 85:15, although this is not essential.
  • the intrinsic viscosity of the copolymer is preferred to be from 0.60 to 1.50 (determined in dimethylformamide at 30°C), but this is not limitative.
  • the contents of the polycarbonate resin and the graft polymer or its mixture with the copolymer is from 20 to 80% by weight (preferably from 30 to 70% by weight) and from 80 to 20% by weight (preferably from 70 to 30% by weight), respectively.
  • the polycarbonate resin is contained in a higher amount than 80% by weight, the melt viscosity of the resulting composition on the molding becomes too high so that the molding property is deteriorated. Further, the weld strength is not improved.
  • the polycarbonate resin is contained in a smaller amount than 20% by weight, the heat resistance is lowered.
  • the copolymer When the copolymer is employed, its amount is not more than 90% by weight on the basis of the combined amount of the graft polymer and the copolymer. When the amount exceeds 90% by weight, satisfactory impact resistance is not obtainable.
  • a polyolefin or a certain plasticizer is incorporated into a blend comprising the polycarbonate resin and the graft polymer with or without the copolymer.
  • polyethylene having a molecular weight of not less than 2,000 or polypropylene having a molecular weight of not less than 5,000 or their mixture.
  • the amount of the polyolefin in the composition is from 0.2 to 10 parts by weight to 100 parts by weight of the blend. When the amount is less than 0.2 part by weight, any improvement of the weld strength and the solvent resistance is not produced. When more than 10 parts by weight, the impact strength is markedly lowered, and the weld strength is not improved.
  • the plasticizer used in the invention is the one having a light transmission of not less than 70% when determined on the film of 20 f..lm in thickness prepared by a solution of the plasticizer (0.25 g) and acrylonitrilestyrene copolymer (weight ratio of acrylonitrile and styrene being 30:70; 0.75 g) in acetone (10 ml) while drying under the atmospheric condition. Further, the bleeding of the plasticizer is apt to be produced at the surface of the molded product with the resulting composition.
  • These plasticizers may be employed alone or in combination.
  • the amount of the plasticizer in the composition is from 0.5 to 20 parts by weight to 100 parts by weight of the blend. When the amount is less than 0.5 part by weight, any improvement of the weld strength is not produced. When the amount is more than 20 parts by weight, the heat resistance is remarkably deteriorated.
  • the graft polymer and the copolymer as above stated may be respectively produced by conventional procedures such as emulsion polymerization, suspension polymerization, bulk polymerization, emulsion-suspension polymerization or bulk suspension polymerization.
  • thermoplastic composition Preparation of the thermoplastic composition may be achieved by mixing the said essential and optional components by the aid of a conventional mixing apparatus such as a roll or Banbury's mixer.
  • a conventional mixing apparatus such as a roll or Banbury's mixer.
  • any additive such as a pigment, a dispersant, a lubricant, a filler, a stabilizer, an antistatic agent and a modifier may be incorporated therein.
